LUBRIcAToR-FILLING VALVE.

Application filed September 18, 1916.

To all cv/1.0m t may concern:

Be it known that we, Jol-1N H. lVATrEns and VILLIAM H.' BEAN, citizensof the United States, residing at Anniston, in the county of Calhounand-State of Alabama, have invented certain new and useful, Improvementsin Lubricator-Filling Valves; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. y

This invention relates to improvements in lling valves for lubrieatorsand the like, and the principal object isV to provide a device of thischaracter which, when connected with the lubricator will effectivelyclose the inlet thereof, yet readily allowing oil or other liquids to bepoured into the latter at will.

An additional object isto provide a filling spout in connection with thevalve whose cover is so connected to the valve stem that the valve willbe opened when the cover is raised.

Still another object is to provide a filling valve of simpleconstruction which can be very inexpensively manufactured and yet whichwill be very efficient in operation.

'Vith these and many other objects in view, the invention resides in thefeatures of construction, combination and arrangement of parts whichwill be more particularly pointed out and described in the specificationand claims.

In the accompanying drawings:

serial No. 120,814.

Fig. 7 is a horizontal section on the line 7 7 of Fig. 5.

Referring to the drawings it will be seen that two forms of fillingvalves are illustrated, the preferred form being shown in Figs. l to 1l,and the modified form in Figs. 5 to 7. The preferred form of valvecomprises a valve casing lpreferably rectangular in cross section andprovided with a reduced threaded end 2 foi-,connecting the device with alubricator or other liquid container. Any other shape of casing might beprovided, this particular form being merely illustrated for the sake ofconven- 'ience.

The casing is provided with a filling spout preferably formed integrallytherewith, said spout communicating with the interior of the casingwhereby oil or other liquids may be permitted to enter the lubricator byway of the casing. This filling spout is provided with a cover orclosure 8 which normally covers the inlet and prevents dirt and otherforeign matter from entering the casing. The cover is hinged to thecasing by means of a pivotrpin 9 which extends through a lug or lingerl0, the latter -extending into the upper end of the valve casing.

'The lower or reduced end 2 of the valve casing is provided with a valveseat 1l in which a valve 5 normally rests. This valve is provided with avalve stem G which extends longitudinally substantially throughout thelength of the easing. In order to guide the valve stem during theopening and closing ofthe valve 5 a combined stop and guide flange 8 isformed in the bore of the casing l. rIhis flange is formed integrallywith the casing and surrounds the stem (i. The upper end of the latterhas a cotter pin or the like extending therethrough, between which andthe flange 8 is disposed an expansion helical spring 7, the samesurrounding the upper end of the valve stem 6. This construction causesthe valve 5 to be normally in engagement with the seat 4 so that noliquidcan enter or leave the lubricator until the valve stem 6 isdepressed against the tension of its spring 7.

From Fig. 3 it will be seen that the finger 10 is dispose-d above theuppei` end of the valve stem G in order that when said cover 8 is raisedthe cam face 11 of the finger will engage said stem and simultaneouslyopen the valve 5. l/Vhen the cover has been raised to its fullest extentthe flat portion 12 of the finger 10 will engage the fiat end of thevalve stem (i so that both the valve and the cover will remain openuntil the parts are manually disengaged. lVhen the inlet of the fillingspout 3 has thus been opened a continuous passageway is provided betweenthe latter and the lubricator or other receptacle upon which the deviceis mounted, thereby allowing oil or other liquid to be poured into thereceptacle. As soon as a sufficient quantity has been deposited thecover 8 is closed, thus causing the linger 1() to be disengaged from thestem G and permitting the valve 5 to close.

The form of filling valve shown in Figs. 5 to 7 is somewhat diierentfrom the first described device, but it embodies the same general ideaand a majority of its parts. The valve casing of this modied fillingplug is designated by the numeral 15 and is provided with a reduced andthreaded end 1G for the same purpose as the end 2v of the other form.The lower end of this valve casing is also provided with an'angularportion 17 which is adapted to be engaged by a wrench to facilitate inconnecting the casing with its lubricator. The upper end of the casingwhich may be of any desired configuration is also reduced and externallythreaded as shown at 18. The purpose of this last named part willpresently appear. The casing 15 has a central bore similar to the casing1 and hascommunicating therewith a filling spout 19.

lVithin the casing 15 is formed an inwardly extending combined stop andguide flange 2O in which the valve stem 21 of a valve 22 slides, saidvalve engaging a valve seat 23 at the end of the reduced portion 16. Theflange 20 surrounds the stem 21 and acts as a stop against which one endof a helical expansion spring 24; abuts, the other end of said springengaging a head 25 which is screwed upon or otherwise detachablyconnected with the upper end of the stem 21. rThis spring 24 holds thevalve 22 normally closed since it bears against the flange 20 and thehead 25. Y

So long as the tension of the spring holds the valv 22 closed no oil orother liquid can enter the lubricator with which the valve casing 15 isconnected. Therefore it is necessary to force the head 25 downwardlyagainst said spring so as to disengage the valve from its seat 3. Inorder to readily accomplish this an internally threaded cap 26 isscrewed on the reduced portion 18 of the casing. This cap is preferablyprovided with a knurled or otherwise roughened gripping portion 27 tofacilitate the rotation thereof. As the head 25 of the valve 21 projectsabove the top of the valve casing 15 it will be engaged by the cap 2Gwhen the same is threaded downwardly, thus opening the valve 22 andpermitting liquids to be poured into the lubricator through the fillingspout 19. After the lubricator is full the cap is screwed upwardly topermit the expansion spring 24 to close the valve.

From the foregoing description it is obvious that we have producedextremely simple lubricating filling valves which will be very efficientin operation, and because of their simple nature can be inexpensivelymanufactured.
